What is the Normal Range of GFR?

The glomerular filtration rate (GFR) is a crucial indicator of renal function, which measures how efficiently the kidneys filter waste products and excess fluids from the blood. A normal range of GFR varies among individuals, and it depends on factors such as age, sex, race, body surface area, and laboratory methods used to calculate it.

In general, a 'normal' GFR is usually above 90 milliliters per minute per 1.73 square meters (ml/min/1.73m2). However, this range may be adjusted based on an individual's specific characteristics. For instance, a person with a high body mass index (BMI) or those who have undergone amputations may require different GFR ranges.

It is essential to note that the estimated glomerular filtration rate (eGFR) is a calculated value based on serum creatinine levels, age, sex, and race. While eGFR is useful for estimating kidney function, it is not always accurate and should be interpreted with caution.

A 20% rise in creatinine while eGFR is above 60 may still indicate a real change in GFR, even if the value appears to be within the normal range. If you are concerned about your GFR levels or have questions regarding your specific situation, it is best to consult with your healthcare provider.

In conclusion, the normal range of GFR varies among individuals and depends on several factors. Understanding your GFR levels and how they relate to your overall health can help you make informed decisions about your care. If you are experiencing symptoms related to kidney function or have concerns about your eGFR, consult with your healthcare provider for personalized guidance.
